Sayfa 52Let L\ be a strongly elliptic second order matrix operator with coefficients infinitely
smooth in fi and coinciding with the coefficients of L\ in a strip near the boundary.
We compare the corresponding Poisson operators V\ and V\. It suffices to show ...

Sayfa 129We note also that the coefficients mj(x) are finite combinations of the coefficients
m°{x) and the coefficients of the Taylor expansions of T"(A, x) at A = 00.
Proposition 3. The numbers k\ and K2 in (66) satisfy the equation (68) m + k2 = 0.
Proof.

Sayfa 136Thus, $2 is rational in A with coefficients holomorphic in x. In its turn, this implies
exactly the same properties for F. Moreover, F(X, x) is holomorphically invertible
in w x D$»{xo), because so are <b2(X,x) and H(\). Finally, we see that T2BT{1 ...
